todays class about obesity

I was pretty amazed at the way the debate over Jordin Sparks went.  I could not believe that a person should not deserve to win something based on their physical appearance.  While obesity can pose serious health issues like diabetes, is the opposite side of the spectrum of being under weight that much better?  I think that it is a persons choice whether or not they wish to change their body.  As long as they are happy with the way they look and understand the risks that may come with it, then they can go for it.  Look at steroids.  People know the harmful risks that come with steroids yet professional athletes choose to take them.  I think it is their choice.  If they want serious health side effects later on in life, then they can go ahead, shoot up and be superman for a game.
